| 1 | Enhanced physicochemical and biological properties of C/Cu dual ions implanted medical titanium显示文摘It is increasingly popular for titanium and its alloys to be utilized as the medical implants.However,their bioinert nature and lack of antibacterial ability limit their applications.In this work,by utilizing plasma immersion ion implantation and deposition(PIII&D)technology,the titanium surface was modified by C/Cu co-implantation.The mechanical property,corrosion resistance,antibacterial ability and cytocompatibility of modified samples were studied.Results indicate that after C/Cu co-implantation,copper nanoparticles were observed on the surface of titanium,and titanium carbide existed on the near surface region of titanium.The modified surface displayed good mechanical property and corrosion resistance.The Cu/C galvanic corrosion existed on the titanium surface implanted by C/Cu dual ions,and release of copper ions can be effectively controlled by the galvanic corrosion effect.Moreover,improved antibacterial performance of titanium surface can be achieved without cytotoxicity. | Chao Xia Xiaohan Ma Xianming Zhang Kunqiang Li Ji Tan Yuqin Qiao Xuanyong Liu | 2020 | Bioactive Materials2020，5，2： | 5 |
| 2 | UV/H2O2 oxidation of tri(2-chloroethyl) phosphate: Intermediate products, degradation pathway and toxicity evaluation显示文摘Tri(2-chloroethyl) phosphate(TCEP) with the initial concentration of 5 mg/L was degraded by UV/H2O2 oxidation process. The removal rate of TCEP in the UV/H2O2 system was 89.1% with the production of Cl-and PO4^3- of 0.23 and 0.64 mg/L. The removal rate of total organic carbon of the reaction was 48.8% and the pH reached 3.3 after the reaction. The oxidative degradation process of TCEP in the UV/H2O2 system obeyed the first order kinetic reaction with the apparent rate constant of 0.0025 min^-1( R^2 = 0.9788). The intermediate products were isolated and identified by gas chromatography-mass spectrometer. The addition reaction of HO · and H2O and the oxidation reaction with H2O2 were found during the degradation pathway of 5 mg/L TCEP in the UV/H2O2 system. For the first time, environment risk was estimated via the 'ecological structure activity relationships' program and acute and chronic toxicity changes of intermediate products were pointed out. The luminescence inhibition rate of photobacterium was used to evaluate the acute toxicity of intermediate products. The results showed that the toxicity of the intermediate products increased with the increase of reaction time, which may be due to the production of chlorine compounds. Some measures should be introduced to the UV/H2O2 system to remove the highly toxic Cl-containing compounds, such as a nanofiltration or reverse osmosis unit. | Qiuyi Ji Huan He Zhanqi Gao Xiaohan Wang Shaogui Yang Cheng Sun Shiyin Li Yong Wang Limin Zhang | 2020 | Journal of Environmental Sciences2020，32，12： | 4 |
| 3 | Terahertz time-domain spectroscopy of some pentoses显示文摘The well-resolved absorption spectra of D-xylose, D-ribose, D-arabinose, D-lyxose and other related substances in the spectral region between 0.3 and 2.0 THz are measured using tera- hertz time-domain spectroscopy (THz-TDS) at 295 K. Comparing the absorption spectra of different chemicals, we can distinguish the samples easily. Thus THz-TDS is demonstrated to be a power and characteristic spectral tool, which is highly sensitive to the minor changes of the molecular structures and can be applied to detect and analyze similar materials. | GE Min ZHAO Hongwei JI Te YU Xiaohan WANG Wenfeng LI Wenxin | 2006 | Science China Chemistry2006，49，3： | 3 |
| 4 | Special interstitial route can transport nanoparticles to the brain bypassing the blood-brain barrier显示文摘Nowadays,nanoparticles(NPs)are considered to be ideal tools for bioimaging and drug delivery.Although increasing research has focused on NP biodistribution,transportation in the interstitial architecture has been neglected.The entire body is connected by the interstitial architecture,which can provide a long-range and direct pathway for NP biodistribution in a nonvascular system.In this study,we report that 10-nm gold NPs injected directly into the interstitial architecture of the tarsal tunnel of rats(intervaginal space injection(ISI))were delivered to the brain without crossing the blood-brain barrier.Furthermore,NaGdF4 nanoparticles were used to explore the transportation route by magnetic resonance imaging.The results demonstrated that,after ISI,the NaGdF4 nanoparticles were transported through the perivascular interstitial space of the carotid arteries and brain vessels to the brain.This is a special nonvascular transportation route like a stream based on the interstitial architecture that provides an alternative pathway for NP biodistribution. | Nan Hu Xiaoli Shi Qiang Zhang Wentao Liu Yuting Zhu Yuqing Wang Yi Hou Yinglu Ji Yupeng Cao Qian Zeng Zhuo Ao Quanmei Sun Xiaohan Zhou Xiaochun Wu Dong Han | 2019 | Nano Research2019，12，11： | 2 |
| 5 | A rapid real-time recombinase polymerase amplification assay for diagnosis of acute hepatopancreatic necrosis disease in shrimp显示文摘Acute hepatopancreatic necrosis disease(AHPND)is an emerging disease in the shrimp farming industry with a high mortality rate that causes serious economic losses in Asia,Africa,and America[1].AHPND is also known as early mortality syndrome because of its early onset of the disease at 5-30 days of shrimp postlarvae stocking and a high mortality rate up to 100%.Symptoms of AHPND include lighter hepatopancreas,atrophy,jejunal empty stomach,softened carapace,and loss of vitality.AHPND is caused by infection of special strains of Vibrio parahaemolyticus(referred to VPAHPND in this study)containing the 69-kb pVA1 plasmid with the binary toxic Photorhabdus insect-related genes PirA and PirB(referred to PirAB in this study)[2].In January 2016,the World Organization for Animal Health(OIE)added AHPND to the OIE List of Aquatic Animal Diseases.Rapid,sensitive,and reliable diagnosis assays for AHPND are demanded by the shrimp farming industry to prevent the disease and reduce economic loss. | Haiyi Yu Xiaohan Yang Juan Zhang Haitao Yang Panpan Zhao Hui Shen Ge Jiang Jing Ji Jingquan Dong Song Gao | 2021 | Acta Biochimica et Biophysica Sinica2021，53，3： | 2 |
| 6 | Hatschek's pit and origin of pituitary gland显示文摘Pituitary gland,or pituitary for short,is characteristic of all vertebrates.As a“master gland”controlling a multitude of important functions in the body,its evolutionary origin has been an object of investigations of evolutionary biology for two centuries.Previous morphological,ultrastructural and immunohistochemical studies suggested the homology of the Hatschek’s pit of amphioxus and vertebrate pituitary.Developmental genetics study showed that the development of Hatschek’s pit and vertebrate pituitary is both subject to regulation by the common genes such as Pit1,Lhx3 and BMP3b.Our recent studies demonstrated that the Hatschek’s pit is able to secrete growth hormone(GH)-like hormone and thyroid-stimulating hormone(TSH)-like hormone that both play functions similar to vertebrate GH and TSH.We thus think that the emergence of Hatschek’s pit represents one of important events during endocrine network evolution,which laid a foundation for the subsequent formation of a hypothalamic-pituitary system in vertebrates. | Shicui Zhang Xiaohan Ji | 2022 | Acta Oceanologica Sinica2022，41，12： | 1 |

| 10 | Equilibrium electron beam parameters of the High Energy Photon Source显示文摘Purpose The physics design of the High Energy Photon Source(HEPS)was finished after many times of iteration.Hereby,the typical equilibrium electron beam parameters corresponding to the proposed two baseline operation modes in the baseline design of HEPS are presented.Methods To compute the equilibrium parameters of the electron beam,the lattice parameters,RF parameters,and the parameters of the insertion devices(IDs)were determined first.Furthermore,it is more precise to use the full-current electron beam parameters in the estimations of the performance of the synchrotron light.Therefore,not only the single-particle dynamics but also the current-dependent collective effects need to be considered in the computations of the full-current,equilibrium parameters of the electron beam.Both analytic computations and multi-particle tracking simulations were carried out.Results The full-current,equilibrium parameters of the electron beams in the HEPS storage ring are presented in this paper.Moreover,the main beam parameters in the injector(the booster and the LINAC),corresponding to the two baseline operation modes of the storage ring,are also presented.Conclusion The typical electron beam parameters corresponding to the two baseline operation modes are given in detail in this paper. | Haisheng Xu Cai Meng Yuemei Peng Saike Tian Na Wang Xiaohao Cui Chongchong Du Zhe Duan Yuanyuan Guo Ping He Xiyang Huang Daheng Ji Hongfei Ji Yi Jiao Jingyi Li Nan Li Xiaoyu Li Xiaohan Lu Pengfei Liang Weimin Pan Huamin Qu Bin Wang Jiuqing Wang Yuanyuan Wei Jinyu Wan Gang Xu Fang Yan Chenghui Yu Sen Yue Xiang Zhang Yaliang Zhao | 2023 | Radiation Detection Technology and Methods2023，7，2： | 0 |
| 11 | Self-Assembled Porous-Reinforcement Microstructure-Based Flexible Triboelectric Patch for Remote Healthcare显示文摘Realizing real-time monitoring of physiological signals is vital for preventing and treating chronic diseases in elderly individuals. However,wearable sensors with low power consumption and high sensitivity to both weak physiological signals and large mechanical stimuli remain challenges.Here, a flexible triboelectric patch(FTEP) based on porous-reinforcement microstructures for remote health monitoring has been reported. The porousreinforcement microstructure is constructed by the self-assembly of silicone rubber adhering to the porous framework of the PU sponge. The mechanical properties of the FTEP can be regulated by the concentrations of silicone rubber dilution. For pressure sensing, its sensitivity can be effectively improved fivefold compared to the device with a solid dielectric layer, reaching 5.93 kPa^(-1) under a pressure range of 0–5 kPa. In addition, the FTEP has a wide detection range up to 50 kPa with a sensitivity of 0.21 kPa^(-1). The porous microstructure makes the FTEP ultra-sensitive to external pressure, and the reinforcements endow the device with a greater deformation limit in a wide detection range. Finally, a novel concept of the wearable Internet of Healthcare(Io H) system for real-time physiological signal monitoring has been proposed, which could provide real-time physiological information for ambulatory personalized healthcare monitoring. | Hao Lei Haifeng Ji Xiaohan Liu Bohan Lu Linjie Xie Eng Gee Lim Xin Tu Yina Liu Peixuan Zhang Chun Zhao Xuhui Sun Zhen Wen | 2023 | Nano-Micro Letters2023，15，7： | 0 |
| 12 | Thoracic interstitial injection of drug-liposomes in mice for treating atherosclerosis显示文摘Intervaginal space injection(ISI)is a novel mode of administration investigated over the last decade.After injecting nanoparticles into the intervaginal space,they can be transported along low flow resistance channels into the interstitial space.This transport has a certain delivery direction,and site-specific injection can work on specific organs or tissues.In this study,the thorax,a new ISI site in the interstitial surrounding the internal thoracic artery named the thoracic interstitial injection(tISI)was investigated.To prove the targeting ability of the tISI,two sizes of gold nanoparticles(AuNPs)(47 and 87 nm)were administered to mice.After 1 h,the biodistribution of AuNPs in the tissues was measured via single particle inductively coupled plasma mass spectrometry(spICP-MS).The results showed that the concentration of AuNPs in the aorta after tISI injection was significantly higher than that after intravenous injection.Moreover,fewer nanoparticles with larger particle sizes were observed to have entered the blood and were better targeted to the aorta.Thereafter,tanshinone IIa sodium sulfonate liposomes were administered for the treatment of aortic atherosclerosis.The proportion of aortic plaques in atherosclerotic Apoe-/-mice administered via tISI was significantly lower than that in other model animals(P<0.001).Furthermore,the proteoglycan content and CD68-positive cell count in the plaques were significantly reduced.The vascular elastic fibers at the plaque site were thickened,and fractures were reduced.tISI was,therefore,determined to be an effective strategy for the treatment of atherosclerotic aortic plaques. | Tun Yan Huizhen Sun Yahong Shi Ya Gao Xi Lu Kai Li Yuting Zhu Qiang Zhang Tingting Li Zhongxian Li Xiaohan Zhou Yuting Guo Yinglu Ji Xiaoli Shi Dong Han | 2023 | Nano Research2023，16，4： | 0 |
| 13 | Geographical distribution of Aspergillus flavus in peanut harvest period in China显示文摘In order to grasp the distribution of Aspergillus flavus in the soil of peanut production areas in China,A.flavus biomarkers were tested on 555 soil samples from 37 sampling points in 17 provinces,peanut fields in four agroecological zones(Southern area,Yangtze River Basin,Northern area,Northeast area).The results showed that(1)the cultivation amount of A.flavus per gram of soil in the Yangtze River Basin is 1.30 times that of the southern area,1.56 times that of the northern area,and 6.20 times that of the northeast area,with obvious regional characteristics.(2)In the Yangtze River basin,the change of longitude in the east-west direction has no direct impact on the cultivation amount of A.flavus per gram of soil.(3)In the east coast,the A.flavus cultivated per gram of soil increased first and then decreased with the increase of latitude from south to north.(4)A.flavus can be isolated in the soil samples above 1000 m.Field pollution is an important source of aflatoxin contamination in peanut.The study on the distribution of A.flavus in soil in China could provide theoretical support for the early warning and prevention and control measures of aflatoxin contamination in peanut. | Xiaohan Liu Jiayun Fu Mingbo Wen Haohua Gu Pingping Ji Xiaofeng Yue Xiaoqian Tang Meijuan Liang Yang Zhou Qi Zhang Peiwu Li | 2023 | Oil Crop Science2023，8，2： | 0 |
| 14 | Focus on perovskite emitters in blue light-emitting diodes显示文摘Blue perovskite light-emitting diodes(PeLEDs)are essential in pixels of perovskite displays,while their progress lags far behind their red and green counterparts.Here,we focus on recent advances of blue PeLEDs and systematically review the noteworthy strategies,which are categorized into compositional engineering,dimensional control,and size confinement,on optimizing microstructures,energy landscapes,and charge behaviors of wide-bandgap perovskite emitters(bandgap>2.5 eV).Moreover,the stability of perovskite blue emitters and related devices is discussed.In the end,we propose a technical roadmap for the fabrication of state-of-the-art blue PeLEDs to chase and achieve comparable performance with the other two primary-color devices. | Xiaoyu Yang Li Ma Maotao Yu Hao-Hsin Chen Yongqiang Ji An Hu Qixuan Zhong Xiaohan Jia Yanju Wang Yuzhuo Zhang Rui Zhu Xinqiang Wang Changjun Lu | 2023 | Light(Science & Applications)2023，12，8： | 0 |
